How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.

Toyota recalls 52k units of 2011-2012 Avalon for potential short circuit

Toyota is issuing a recall for roughly 52,000 examples of its 2011 and 2012 Avalon sedans in the US because a possible short circuit in the wiring for audio system's subwoofer may cause a fire. According to Toyota, it's possible for the subwoofer's wires to move out of position if contacted by cargo in the trunk. If one of the wires then contacts the metal frame of the speaker, it could trigger a short circuit. "If this occurs, the subwoofer could overheat, increasing the risk of a fire," according to the automaker. "There were two reports of thermal events – no outright fires," said Toyota spokesperson Cindy Knight to Autoblog. Toyota reports there are no reports of injuries, fatalities or crashes from this problem. Dealers will repair this problem at no cost, but until then, they will immediately disconnect the rear subwoofer as a precaution for owners. The recall notices will be sent out in mid-February, according to Knight. TOYOTA RECALLS CERTAIN 2011-2012 MODEL YEAR AVALON VEHICLES TORRANCE, Calif., January 28, 2015 – Toyota Motor Sales, U.S.A., Inc., today announced plans to conduct a safety recall of approximately 52,000 Model Year 2011-2012 Avalon sedans. In the involved vehicles, cargo could contact one of the audio system subwoofer wires located inside the trunk, and move the wire out of its normal position. If one of these wires contacts the metal frame of the subwoofer, it may result in an intermittent short circuit. If this occurs, the subwoofer could overheat, increasing the risk of a fire. Toyota is not aware of any crashes, injuries, or fatalities caused by this condition. Owners of the involved vehicles will receive a notification by first class mail. Toyota dealers will provide a repair for the audio system. Until the remedy is available, as a precaution, Toyota dealers will disconnect the rear subwoofer.

Incoming Toyota chairman wants a Supra successor

We'd venture to guess that in recent years, there have probably been almost as many rumors swirling about a Toyota Supra successor than there have been for a mid-engine Corvette. (Case in point: the speculative renderings we came across a few years ago, pictured above.) While we don't expect the Corvette's recipe to change drastically any time soon, it looks like a Supra - or more appropriately a Supra-like car - could be closer than we think.
First, there was an announcement of a BMW-Toyota joint venture. Said venture would, among other things, "Set up a feasibility study to define a joint platform concept for a mid-size sports vehicle."
Upping chances even further, a new Automotive News report claims that incoming Toyota chairman Takeshi Uchiyamada wants a vehicle "comparable" to the Supra. Clearly there are a lot of parties that want a new Supra to happen - to say nothing of enthusiasts - but Uchiyamada might be just the guy to get it done. None of this is proof positive of an impending Supra, to be sure, but winds do seem favorable.
